Inconel 600 vs Hastelloy C-276 vs 316 Stainless Steel for High Pressure Reactors
For many general laboratory reactions, 316 stainless steel is the practical and economical starting point. Alloy 600, commonly known by the Inconel 600 trade name, becomes attractive when high temperature strength and resistance to certain caustic and chloride containing environments are important. Alloy C-276, commonly associated with Hastelloy C-276, is often sele… Read more
Agilent 6890 FID Troubleshooting: Flame, Flow, Baseline and Sensitivity Problems
If an Agilent 6890 FID will not ignite, will not stay lit, has low sensitivity, or develops a noisy or drifting baseline, troubleshoot the system in a logical order:
Confirm hydrogen, air, carrier and makeup-gas supply.
Verify actual detector gas flows rather than relying only on displayed values.
Check for gas leaks.
Inspect the FID jet for restriction or contam… Read more
Agilent 6890 vs 7890 GC: Which Gas Chromatograph Is Right for Your Lab?
The Agilent 6890 remains an excellent value for laboratories running established GC methods, routine FID analysis, environmental testing, hydrocarbon analysis, teaching applications and research workflows where proven performance matters more than having the newest instrument platform.
The Agilent 7890 is generally the better choice for laboratories that need higher throug… Read more

Tissue Homogenizer Selection Guide: How to Choose the Right Homogenizer for Animal, Plant and Fibrous Samples
For most general laboratory tissue homogenization, a rotor-stator homogenizer is one of the best starting points because it can rapidly break animal, plant and fibrous tissue into a uniform suspension using intense mechanical shear.
An ultrasonic homogenizer is often better as a secondary step when the objective extends beyond bulk tis… Read more
